This function returns a list of tuples. The first entry of each
tuple is a string (lsei_name), and the second is a lists built from
lsei_values.
Probably the C data structure is modeled along the lines of a
mapping "lsei_name -> (list of lsei_values)". However, there seems
to be no guarantee that a lsei_name is unique, so I dare not use a
python mapping for this beast...
